There is no hyphenation yet but this is not a serious problem for ragged-right designs. Page layout, what the input should look like, interactive PDF features are more important. Kerning and automatic ligatures and so forth are working, with both OpenType and non-OpenType fonts. However I may do hyphenation prematurely out of curiosity about it. Probably not, though—I’d kind of like to have this thing working. Oh, and another thing to work on may be support for ‘faking’ accented letters.
Finding hyphenation points probably is easy, using a C library I found. The difficulty is incorporating hyphenation points efficiently into the line-breaking routine.
Actually the first thing to do is further clean-up on the OpenType-support code.
